Sea Change: GE’s French Wind Turbine Factory Will Power Germany’s Renewables Revolution
By Tomas Kellner – GE is a relative newcomer to offshore wind. The company explored the field a decade ago and returned to the industry in 2015, when it acquired the energy assets of Alstom, and built its first wind farm in Long Island Sound near Block Island, Rhode Island, last year. As the inaugural offshore wind farm in the United States, the project made a splash even though it holds just five turbines. But Merkur, which will have 66 turbines, is a much bigger beast. “This one is special,” says Pascal Girault, who runs the Saint-Nazaire plant. “Everything is big.”
Girault spent the early part of his career managing supply chains for the car industry, but ramping up production for Merkur is no Sunday drive. Workers in Saint-Nazaire make generators and assemble nacelles for the 6-megawatt GE Haliade turbine. The nacelle is the casing on top of the tower that shelters the generator and other equipment. It includes some 30,000 components.
Adding to the task’s complexity, the composite blades for the machines’ 150-meter-diameter rotors come from GE’s LM Wind Power factory in Spain. The steel segments for the tower are being made in Germany and China. U.S. and European companies supply electronics and mechanical components for the converter and generator. “The scale and the speed of the project are challenging,” Girault says. more> https://goo.gl/GSScqV
